Identifying nearby field T dwarfs in the UKIDSS Galactic Clusters Survey
N. Lodieu, B. Burningham, N. C. Hambly +1
We present the discovery of two new late-T dwarfs identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) Data Release 2 (DR2). These T dwarfs are…
Sources of contamination to weak lensing tomography: redshift-dependent shear measurement bias
Elisabetta Semboloni, Ismael Tereno, Ludovic van Waerbeke +1
The current methods available to estimate gravitational shear from astronomical images of galaxies introduce systematic errors which can affect the accuracy of weak lensing cosmolo…
The JCMT Nearby Galaxies Legacy Survey I. Star Forming Molecular Gas in Virgo Cluster Spiral Galaxies
C. D. Wilson, B. E. Warren, F. P. Israel +20
We present large-area maps of the CO J=3-2 emission obtained at the James Clerk Maxwell Telescope for four spiral galaxies in the Virgo Cluster. We combine these data with publishe…
On the origin of double main-sequence turn-offs in star clusters of the Magellanic Clouds
K. Bekki, A. D. Mackey
Recent observational studies of intermediate-age star clusters (SCs) in the Large Magellanic Cloud (LMC) have reported that a significant number of these objects show double main-s…
Cosmological Systematics Beyond Nuisance Parameters : Form Filling Functions
T. D. Kitching, A. Amara, F. B. Abdalla +2
In the absence of any compelling physical model, cosmological systematics are often misrepresented as statistical effects and the approach of marginalising over extra nuisance syst…
Results from the First Science Run of the ZEPLIN-III Dark Matter Search Experiment
V. N. Lebedenko, H. M. Araujo, E. J. Barnes +35
The ZEPLIN-III experiment in the Palmer Underground Laboratory at Boulby uses a 12kg two-phase xenon time projection chamber to search for the weakly interacting massive particles…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
Introducing a Hybrid Method of Radiative Transfer for Smoothed Particle Hydrodynamics
Duncan Forgan, Ken Rice, Dimitris Stamatellos +1
A new means of incorporating radiative transfer into smoothed particle hydrodynamics (SPH) is introduced, which builds on the success of two previous methods - the polytropic cooli…
The UKIDSS-2MASS Proper Motion Survey I: Ultracool dwarfs from UKIDSS DR4
N. R. Deacon, N. C. Hambly, R. R. King +1
The UKIRT Infrared Deep Sky Survey (UKIDSS) is the first of a new generation of infrared surveys. Here we combine the data from two UKIDSS components, the Large Area Survey (LAS) a…
STAGES: the Space Telescope A901/2 Galaxy Evolution Survey
M. E. Gray, Christian Wolf, Marco Barden +26
We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution ac…
The STAGES view of red spirals and dusty red galaxies: Mass-dependent quenching of star-formation in cluster infall
Christian Wolf, Alfonso Aragon-Salamanca, Michael Balogh +22
We investigate the properties of optically passive spirals and dusty red galaxies in the A901/2 cluster complex at redshift ~0.17 using restframe near-UV-optical SEDs, 24 micron IR…
The Wouthuysen-Field effect in a clumpy intergalactic medium
Jonathan Higgins, Avery Meiksin
We show that, due to the high optical depth of the intergalactic medium to Lyman-alpha photons before the Epoch of Reionization, the Lyman-alpha scattering rate responsible for the…
Parity violation constraints using 2006-2007 QUaD CMB polarization spectra
QUaD Collaboration, E. Y. S. Wu, P. Ade +29
We constrain parity-violating interactions to the surface of last scattering using spectra from the QUaD experiment's second and third seasons of observations by searching for a po…
On the relationship between instability and Lyapunov times for the 3-body problem
D. J. Urminsky, D. C. Heggie
In this study we consider the relationship between the survival time and the Lyapunov time for 3-body systems. It is shown that the Sitnikov problem exhibits a two-part power law r…
Star Formation Around Super-Massive Black Holes
I. A. Bonnell, W. K. M. Rice
The presence of young massive stars orbiting on eccentric rings within a few tenths of a parsec of the supermassive black hole in the Galactic centre is challenging for theories of…
A Numerical Testbed for Hypotheses of Extraterrestrial Life and Intelligence
Duncan Forgan
The search for extraterrestrial intelligence (SETI) has been heavily influenced by solutions to the Drake Equation, which returns an integer value for the number of communicating c…
A search for spectroscopic binaries in the galactic globular cluster M4. Based on 5973 individual spectra collected at VLT
V. Sommariva, G. Piotto, M. Rejkuba +4
We present a large multi-epoch high resolution spectroscopic investigation for the search of binary candidates in the Galactic Globular Cluster (GGC) M4. The aim of our work is the…
Statistical Analysis of Galaxy Surveys - I. Robust error estimation for 2-point clustering statistics
Peder Norberg, Carlton M. Baugh, Enrique Gaztanaga +1
We present a test of different error estimators for 2-point clustering statistics, appropriate for present and future large galaxy redshift surveys. Using an ensemble of very large…
AGN accretion disks as spatially resolved by polarimetry
Makoto Kishimoto, Robert Antonucci, Omer Blaes +4
A crucial difficulty in understanding the nature of the putative accretion disk in AGNs is that some of its key intrinsic spectral signatures cannot be observed directly. The stron…

Alexandre Refregier, Adam Amara, Thomas Kitching +1
Aims: The interactive software package iCosmo, designed to perform cosmological calculations is described. Methods: iCosmo is a software package to perform interactive cosmological…
Vortices in self-gravitating disks
G. R. Mamatsashvili, W. K. M. Rice
Vortices are believed to greatly help the formation of km sized planetesimals by collecting dust particles in their centers. However, vortex dynamics is commonly studied in non-sel…
